Hi, your history suggests that you have milder form of sleep disorder. There is a delayed onset of sleep and can be due to committed work, success, stress, unusual happenings make you anxious and it will keep you awake and will lead to delayed onset of sleep.
Once you sleep, your sleep architecture seems to be fine i.e. stages of sleep. You do not need any major therapeutic interventions for your condition. This is common when there is a disturbance in normal sleep pattern.
The therapy for this condition includes retaining of normal circadian rhythm by non-pharmacological therapy which includes; Photo therapy, maintenance of sleep hygiene. You need to go for morning exercises and work out which will make you fresh and active all day and tiredness at the end of day will help you to induce sleep naturally.
Pharmacological therapy includes short course of appropriate sedatives and Hypnotics against prescription. Non-benzodiazepines are effective in delayed onset sleep disorder and help to initiate the sleep.
I suggest you to consult sleep specialist for introduction of non-pharmacological and medical therapy. Take care and regards.
I've been drinking Sleepytime vanilla tea by Celestial Seasonings 30mins before bed. You might want to give it a try.
